Calculate the entropy change of 73.1 g of water that freezes into ice at 273.15 K. ΔHfus for water is 6.01 kJ/mol.

Step 1: FInd the total deltaH by finding how many moles of water you have and multiplying by 6.01.
Step 2: Since this is a reversable reaction, divide by the temperature of freezing to get the entropy change.

The molar warmth of fusion for ice is 6.02-kJ/mol - it is, 6.02-kJ of thermal means is absorbed for each mole of water that melts. 36.0-g x a million mol H?O / 18.0-g H?O x 6.02kJ/mol = 12.0-kJ

I'm not sure about it, there's no data about the initial temperature of the water
